Title: Enhancement of Electrostatic Images.
IPC: G03G13/045
Filed: 1967-09-28
Abstract: 1,199,462. Electroluminescence. RANK XEROX Ltd. 28 Sept., 1967 [29 Sept., 1966], No. 44121/67. Heading C4S. [Also in Division G2] A method for amplifying charge variations in a latent electrostatic charge image comprises forming the image on a surface of a photoconductive material contiguous to or forming a field effect semi-conductor layer, contacting the surface with an electroluminescent layer and applying a potential to produce an electric field at the e.1. layer having an intensity in accord with the conductivity of the f.e.s.c. layer; preferably the f.e.s.c. is able to retain the surface charge when current passes, e.g. Zn, Cd or Pb oxide. A sheet of paper 15 coated with ZnO 17 is placed on a grounded conductor 35, the ZnO is uniformly negatively charged then exposed to an optical image causing discharge over illuminated areas resulting in the reversed charge image. The paper is then placed on an e.1. layer 7 and A.C. applied between adjacent electrodes 8 below the e.1. layer. In illuminated discharged areas the conductivity of the f.e.s.c. ZnO is high and a high current passes through the e.1. layer via the ZnO generating light which results in a further discharge of the charge image. In areas not illuminated the high negative charge reduces the conductivity of the ZnO and little or no current flows through the e.1. material which therefore emits no light and the charge is retained. The process is stopped by removing the paper or stopping the current when it reaches a predetermined value. If the ZnO is on a conductive A1 substrate the electrodes 8 may be replaced by a conductive layer and potential applied between this and the substrate. In another embodiment the latent image is formed on a layer of photoconductive vitreous Se on a f.e.s.c. layer, e.g. vacuum deposited n-type CdS, the layers being separated by an insulating layer. If the p.c. layer is initially charged positive areas of high charge have a high conductivity resulting in decreased contrast. The e.1. material is ZnS: CuCl 2  or ZnS, ZnSe: Cu in P.V.C. resin and electrodes 8 are vapour deposited An or Cu.

[Also in Group IX] A driving belt 82, particularly for spinning or twisting machines, is tensioned by a pulley 81 on a slide 9 acted upon by weight or spring means 8 whose line of action is inclined to the slide so that it simultaneously tensions the belt 82 and holds the slide 9 against its supporting slideway 6. Wear of the slide is thus automatically taken up without producing any free play. As shown, the co-operating sliding surfaces (one or both of which may be of plastic) are flat and are slotted to receive a single spring 8 anchored in selected notches 15. Should the belt 82 break the slide 9 is retained by a hook 10 thereon. In modifications, the co-operating sliding surfaces may be of curved or V section, and the single spring 8 may be replaced by a pair of springs, one on each side of the slide. Such springs may converge or diverge towards their anchorages to restrain the slide laterally ; in one form they are anchored on a centrally-pivoted arm. In a construction dispensing with springs the belt-tensioning pulley, Fig. 11 (not shown), is mounted on a weighted slide engaging a fixed inclined slideway.
